An ant moves at constant speed on the principal axis of concave mirror of focal length f , from a point at distance 5 f
from the pole of the mirror to the focus F of the mirror. During the motion of the ant
(consider the ant as a point), its image formed by the mirror
Statement S1: moves with constant speed
Statement S2: has same velocity as that of the ant when the ant is at center of curvature C of the mirror
Statement S3: moves slower in the beginning and faster towards the end
Statement S4: moves faster in the beginning and slower towards the end
Now, choose the correct option:
